Today the company runs one of the world’s largest networks that powers millions of websites and other Internet properties for customers ranging from individual bloggers to SMBs to Fortune 500 companies. Cloudflare protects and accelerates any Internet application online without adding hardware, installing software, or changing a line of code. Internet properties powered by Cloudflare all have web traffic routed through its intelligent global network, which gets smarter with every request. As a result, they see significant improvement in performance and a decrease in spam and other attacks. Cloudflare was named to Entrepreneur Magazine’s Top Company Cultures list and ranked among the World’s Most Innovative Companies by Fast Company.
At Cloudflare, we’re not looking for people who wait for a polished roadmap; we’re looking for the builders who see the cracks in the Internet that everyone else has simply learned to live with. We value candidates who have the instinct to spot a "normalized" problem and the AI-native curiosity to create a solution using the latest tools. Our culture is built on iteration, leveraging AI to ship faster today to make it better tomorrow, while ensuring that every improvement, no matter how small, is shared across the team to lift everyone up. If you’re the type of person who values curiosity over bureaucracy, and that AI is a partner in solving tough problems to keep the Internet moving forward, you’ll fit right in.

Security at Cloudflare is a focused team committed to helping secure both Cloudflare and our customers. The Threat Detection Automation and Intelligence Team is responsible for identifying, understanding and detecting threats to Cloudflare.
We are seeking an experienced Threat Intelligence Engineer with experience with machine learning data science to join our proactive security team. This role is a critical blend of two disciplines: leveraging Threat Intelligence (TI) to understand the adversary, and then applying advanced Machine Learning and engineering principles to rapidly and effectively defend our organization. The ideal candidate will transform raw threat data into actionable security measures and automated defenses, significantly reducing our mean time to detect (MTTD) and mean time to respond (MTTR) to sophisticated cyber threats.
Intelligence Collection & Analysis: Proactively research, collect, and analyze threat intelligence from various sources (OSINT, commercial feeds, dark web, and internal security events) to understand the current and emerging threat landscape.
Machine Learning and Data Science: Design, implement, and maintain detection use cases for the entire machine learning lifecycle (data ingestion, training, deployment, and inference).
Threat Actor Profiling: Develop detailed profiles of relevant threat actors, their Tactics, Techniques, and Procedures (TTPs) using frameworks like MITRE ATT&CK , and identify potential impacts to the organization.
Actionable Intelligence Dissemination: Produce and disseminate timely, relevant, and actionable intelligence reports and briefings for both technical security teams and executive leadership.
IOC/IOA Management: Engineer the ingestion, enrichment, correlation, and contextualization of Indicators of Compromise (IOCs) and Indicators of Attack (IOAs) into security platforms.
Automated Defense Development: Design, develop, and implement robust automation workflows and playbooks (SOAR) to streamline security operations tasks, including incident triage, alert enrichment, vulnerability management, and threat response actions.
Tool Integration & Optimization: Integrate diverse security tools (e.g., SIEM, EDR, Cloud Security Posture Management, vulnerability scanners, Threat Intelligence Platforms) through APIs and scripting (primarily Python) to create seamless, automated feedback loops.
Process Improvement: Identify manual, repetitive, and time-consuming security processes and engineer scalable automation solutions to increase team efficiency and operational maturity.
Incident Response Support: Provide threat context to support the Incident Response team during active security incidents.
Cross-Functional Partnership: Collaborate with Detection Engineers, Security Engineers, and Software Developers to embed security and intelligence-driven practices into the CI/CD pipeline and corporate infrastructure.
Desirable Skills, Knowledge, and Experience
Understanding of attacker Tools, Techniques and Procedures (TTPs)
Understanding of attack components
Experience threat hunting in a complex network
The ability to read an attack brief or vulnerability report and contextualize the associated risk
Experience validating vulnerability reports and providing impact analysis
Experience performing data gathering and analysis on perceived threats; generating additional contextual data that can be operationalized
Experience with common tools used within Security Operations
Experience utilizing security event information in intelligence analysis
Ability to navigate ambiguity, and provide clarity to complex situations
Ability to work autonomously with a strong sense of urgency, ownership and self drive
Ability to build partnerships and get results across many different stakeholders
Ability to effectively communicate, both verbal and written, to stakeholders regarding relative risk, urgency, and feedback
Highly qualified candidates will have an understanding of nation state motivations and operational capabilities
Experience with Infrastructure-as-Code (IaC) tools like Terraform.
Familiarity with data analysis and visualization tools for threat intelligence
Experience with malware analysis and reverse engineering to extract actionable indicators.
Experience: 4+ years of hands-on experience in a Security Engineering, Cyber Threat Intelligence, or Security Automation role.
Programming: Strong proficiency in at least one scripting/programming language for automation (e.g., Python).
Security Concepts: Deep understanding of the cyber kill chain, threat actor TTPs, common attack vectors, networking protocols, and operating system internals.
Automation Expertise: Proven experience designing and implementing SOAR playbooks and integrating security tools via APIs.
Intelligence Tools: Experience working with commercial and open-source Threat Intelligence Platforms (TIPs) and threat feeds.
Cloud Security: Familiarity with security services and automation in major cloud environments (AWS, Azure, or GCP).

What Makes Cloudflare Special?
We’re not just a highly ambitious, large-scale technology company. We’re a highly ambitious, large-scale technology company with a soul. Fundamental to our mission to help build a better Internet is protecting the free and open Internet.
Project Galileo: Since 2014, we've equipped more than 2,400 journalism and civil society organizations in 111 countries with powerful tools to defend themselves against attacks that would otherwise censor their work, technology already used by Cloudflare’s enterprise customers--at no cost.
Athenian Project: In 2017, we created the Athenian Project to ensure that state and local governments have the highest level of protection and reliability for free, so that their constituents have access to election information and voter registration. Since the project, we've provided services to more than 425 local government election websites in 33 states.
1.1.1.1: We released 1.1.1.1 to help fix the foundation of the Internet by building a faster, more secure and privacy-centric public DNS resolver. This is available publicly for everyone to use - it is the first consumer-focused service Cloudflare has ever released. Here’s the deal - we don’t store client IP addresses never, ever. We will continue to abide by our privacy commitment and ensure that no user data is sold to advertisers or used to target consumers.
